BRIEFING: SPS- 75 is the new designation for the TRS-3D, a
three-dimensional multimode radar designed to perform surveillance, fire-control, gunfire support and helicopter control.
The radar is optimized to track small, fast-moving targets
such as swarming small boats. The SPS- 75 is installed on
Freedom-class LCSs. Beginning with LCS 17, the TRS-4D will
be installed on the Freedom class. The TRS-4D is a software-reprogrammable C-band active electronically scanned array
radar allowing for greater sensitivity to detect smaller targets
with greater accuracy.

SPS- 77 SEA GIRAFFE AMB RADAR
BRIEFING: SPS- 77 is the new designation for the Sea Giraffe,
a three-dimensional agile multibeam (AMB) radar designed
to perform surveillance, fire-control, gunfire support and
helicopter control. The radar is optimized to track small,
fast-moving targets such as swarming small boats, anti-ship missiles and anti-radiation missiles. The Sea Giraffe is
installed on the Independence-class LCSs.

BPS-15/16 RADARS

BRIEFING: The BPS-15/16 radars are installed on submarines
for navigation and surface surveillance. Variants are installed
on all current classes of U.S. submarines. The X-band radars
feature Automatic Radar Plotting Aid support for target tracking in real time, along with user configurable target symbols
to assist in accurately determining past, present and future
target positions. The newest version, being installed on Block
III Virginia-class SSNs, is the BPS- 16(V) 5, fully integrated
with the submarine’s tactical local-area network.

SHIPBOARD ELECTRONIC WARFARESYSTEMS

AUTOMATIC IDENTIFICATION SYSTEM (AIS)

BRIEFING: The AIS is a commercially available shipboard
broadcast VHF maritime band transponder system that can
transmit ship information, including navigation, identification and cargo. AIS is mandated by the International Maritime
Organization for all merchant vessels of more than 300 tons.

Warships are exempt.

AIS significantly increases the ability of the Navy and
allied nations to distinguish between normal and suspicious
merchant ships headed toward U.S. and allied ports. Navy
warships using AIS have observed dramatic increases in situational awareness, ship safety and intelligence gathering. In

2005, Navy leaders identified AIS as an urgent capability and
directed fielding of standalone AIS on all warships by fiscal

2006 and integrated AIS in 2007-2011. AIS was granted RapidDeployment Capability authority in January 2006 and transi-tioned to a program of record in 2008.

BRIEFING: The BLQ- 10 is an advanced signals intelligence
(SIGINT) surveillance system for submarines, designed to
support operations in the littoral or open-ocean environment.
It enables detection, identification (to a specific emitter),
analysis and direction finding of radar and communications signals of interest. The BLQ- 10 also aids in gathering
intelligence. First deployed in 2000, it is being installed as a
common SIGINT suite in all operational Navy submarines.

SLQ- 32 ELECTRONIC WARFARE SYSTEM/
SURFACE ELECTRONIC WARFARE
IMPROVEMENT PROGRAM (SEWIP)
BRIEFING: The SLQ- 32, introduced in the early 1980s, is the
Navy’s primary shipboard electronic warfare system. It has
provided the capability to passively detect threat radar emissions, particularly those from radar-guided anti-ship cruise
missiles, and classify the type of radar. About half of the
fleet’s SLQ-32s, predominantly those on larger ship classes,
also have an active radar jamming capability.

The SLQ- 32(V) systems are undergoing an evolutionary
upgrade through SEWIP, an incremental block upgrade and
replacement program for several classes of Navy combatant
ships. The Block 1A upgrades replace the original signal processor with the COTS Electronic Surveillance Enhancement
processor and the display console with the Navy standard
UYQ- 70, both of which are integrated with improved control
and display software.

Block 1B integrates a standalone SSX- 1 Small Ship
Electronic Support Measures System already in production
at General Dynamics, adding a specific emitter identification
capability. The Coast Guard also has ordered SSX- 1 systems.

Block 1B3, approved for low-rate production in August
2012, provides improved situational awareness.

Lockheed Martin was selected in November 2009 to produce a preliminary design for the Block 2 phase that will entail
more significant improvements, including a new antenna
and receiver. Block 2 was approved for low-rate production
in January 2013. Ten systems were procured, with 14 more
ordered in September 2014 and additional units ordered in
2015. The Block 2 was installed on USS Bainbridge in July 2014
